Description
Summary:The development of a second-generation thermoset steam turbine-generator insulation system is described. Reiterative optimization and selection of materials, material composites, and processes are reported. he resulting new insulation is characterized with respect to its short and longterm electrical properties, thermal and dimensional stability. High priority was assigned to the mechanical properties of the new insulation system.
